The full code itself is very convoluted, long, and novice written, basically I'm trying to send x and z coordinates via rednet from a computer to a separate receiver turtle.

Receiver

rednet.broadcast("Awaiting Input!")
xAxis = rednet.receive() --Have tried tonumber(rednet.receive()) on both same result
zAxis = rednet.receive()
rednet.broadcast(xAxis) --Both values return 2 regardless of what I enter in the sender.
rednet.broadcast(zAxis)

sender

if(irrelevant == "genericstringhere") then
    print(rednet.recieve()) --Awaiting Input!
    io.write("X Axis: ") --Pizzaz
    message = io.read() --Have tried using terms like X and xAxis.
    rednet.broadcast(message) --Broadcast whatever tf I typed in.
    sleep(0.3)
    io.write("Z Axis: ") --More Pizzaz
    message = io.read() --Have tried using terms like Z or zAxis
    rednet.broadcast(message) --Broadcast whatever tf I typed in. again.
    print(rednet.receive()) --Receive xAxis value from sender.
    print(rednet.receive()) --Receive zAxis value from sender.
end

Both results at the end of execution return 2 instead of the value I input in io.read() I have tried "tonumber()" "tostring()" and every combination of the two and can't seem to get it to work.

Per the documentation for rednet.receive:

Returns number senderID, any message, string protocol

The 2 you're seeing is the sender ID, not the message. Instead of xAxis = rednet.receive(), do senderId, xAxis = rednet.receive(), and similarly for everywhere else you assign its value. (If you were wondering why print showed you numbers before the messages, that's why.)
